PASSAIC — Police arrested a Queens woman Thursday after she allegedly offered sex to an undercover officer at a city massage parlor.

According to Passaic County Sheriff Richard Berdnik, the detective called New Star Spa on Main Avenue after seeing an ad posted on the internet. He was able to make an appointment for a massage, and was greeted by 27-year-old Ying Ai Hong upon arrival.

"He was led to a private room, where the paid for a massage," Berdnik said. "After the massage was over, he was asked if he wanted to be masturbated, wanted oral sex, or if he wanted to have sexual intercourse."

The detective then signaled to other officers stationed outside, who took Hong into custody. The owner of the spa was not present at the time, but police took her information and plan to conduct a follow-up investigation, Berdnik said.

Hong was unable to provide identification after her arrest, and is being held at Passaic police headquarters because she is believed to be residing in the country illegally.
